"We took the engine to pieces and scanned the components. Then we printed two copies. It was a complex project that took a year," Ms Wu said in a statement on Thursday.

The scientists are confident the breakthrough will lead to more advanced manufacturing work in Australia, and say the "proof of concept" has already created opportunities for local firms.

"No one has printed an entire engine commercially yet," said Ben Batagol from Amaero Engineers, the Monash University company making the technology available to Australian industry.

"The project is a spectacular proof of concept that's leading to significant contracts with aerospace companies," Mr Batagol added.

After three decades in relative obscurity, 3D-printing, which employs lasers to "print" objects from metals or plastics according to a digital design, is becoming a much talked-about area of technology.

Computer giant Hewlett-Packard has announced it will put an ultra-fast 3D printer on the market by 2016.

General Electric and Boeing have also expressed interest in the technology.
